The Dark Knight has completely redefined what a comic book movie should be. Hands down.
Also, hats off to Heath Ledger's role in the film which completely outshines, and, at times, washes out, everyone else's contribution, and is by far his most dark and chilling role to date. Leaving the theatre is bitter-sweet for obvious reasons, which needn't be stated here. He will be missed.
But, as said previously, this movie is very entertaining. You almost forget the minor problems or issues you find in it. It's set a new bar for not only comic movies, but film in general. I feel bad for any movie, even another sequel of this one, having to follow this act.
